As you can see from the video, exploiting an unsuspecting Mt Gox user into giving up their (hard earned?) bitcoins wouldn't be that difficult. This is just the tip of the iceberg and I'm sure we will see many more attacks against bitcoin itself and supporting sites.

Thanks for the good information. This is something to watch out for but not anything unique to mtgox.com especially since they enabled SSL. If it is not an SSL connection to mtgox then there is a PROBLEM!
